A grand watch that has hit the big time: Ahoi! Although it looks dashing in a suit, its natural habitat is the water. This automatic watch holds firm down to 200 meters, the blue-black textile strap is waterproof, the crown guard protects from knocks and shocks. And the luminous indexes and hands tell the time even in the murkiest of deep-sea waters.
